Overview of Alarms
NCK alarms
16420 Channel %1 block %2 axis %3 programmed repeatedly
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: It is not allowed to program an axis more than once.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Delete the axis addresses that have been programmed more than once.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16421 Channel %1 block %2 angle %3 programmed repeatedly in the block
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Angle
Definitions: It is not allowed to program more than one PHI or PSI angle for an orientation vector in the same block.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16422 Channel %1 block %2 angle %3 programmed repeatedly in the block
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Angle
Definitions: It is not allowed to program more than one rotation angle THETA for the orientation in one block. The
angle of rotation can either be programmed explicitly with THETA or by programing with Euler angles
or RPY angles.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16423 Channel %1 block %2 angle %3 programmed repeatedly in the block
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Angle
Definitions: It is not allowed to program more than one polynomial for the orientation rotation angle with PO[THT]
in one block.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
